Abstract

Adults and immatures of Diaphorina teucrii sp. nov. (Hemiptera, Liviidae, Euphyllurinae) and adults of Tamarixia dorchinae sp. nov. (Hymenoptera, Eulophidae, ) from Israel are described, diagnosed and illustrated. D. teu- crii sp. nov. develops on Teucrium capitatum (Lamiaceae), representing a family which was previously not recorded as a psyllid host from Israel, and is parasitised by Tamarixia dorchinae sp. nov. Identification keys are provided for the Dia- phorina and Tamarixia species occurring in Israel.

Introduction

Diaphorina (Psylloidea, Liviidae, Euphyllurinae) is a of plant-sap feeding psyllids which comprises 78 described species restricted to the Old World (Loginova 1978; Ouvrard 2014). In addition, there are probably just as many undescribed species (BMNH, NHMB data). The genus includes (Kuwayama), the vector of the causal agent of huanglongbing (HLB, greening disease). Originating probably from China, the species has been introduced into Southeast Asia, India, the Arabian Peninsula and the Americas. It constitutes today the economically most important pest. Psyllids are generally very host specific, and related psyllid species tend to develop on related host species (Burckhardt et al. 2014). Diaphorina is exceptional in that plants of at least 18 families belonging to 10 orders are colonised (Hollis 1987). Also reasonably host specific are the parasitoids associated with jumping plant-lice such as the cosmopolitan Tamarixia (Chalcidoidea, Eulophidae, Tetrastichinae) which comprises 51 described species associated mostly with Psylloidea, in addition to two species with Aphidoidea (Hemiptera) and one questionably with Agromyzidae (Diptera) (Zuparko et al. 2011; Noyes 2014; Yefremova et al. 2014). Several Tamarixia species are used for the biological control of jumping plant-lice, such as T. radiata (Waterston) for Diaphorina citri (Halbert & Manjunath 2004). Recently an unknown Diaphorina species with an associated, equally unknown, Tamarixia species was discovered on Teucrium capitatum L. (Lamiaceae) in the Negev desert, Israel. In Israel six Diaphorina spp. have been previously recorded: D. aegyptiaca Puton from Cordia (Cordiaceae), D. chobauti Puton from Convolvulus (Convolvulaceae), D. lamproptera Burckhardt from Zygophyllum (Zygophyllaceae), D. luteola Loginova from Solanum (Solanaceae), D. lycii Loginova from Lycium (Solanaceae) and D. putonii (Löw) from Thymelaea (Thymelaeaceae), as well as 14 Tetrastichinae species: Aprostocetus bucculentus (Kostjukov), A. ceroplastae (Girault), A. hagenowii (Ratzeburg), A. neglectus (Domenichini), A. sicarius (Silvestri), A. toddaliae (Risbec), Baryscapus ceroplastophilus (Domenichini), B. crassicornis (Erdös), B. servadeii (Domenichini), Leptocybe invasa Fisher & LaSalle, Minotetrastichus platanellus (Mercet), Pronotalia carlinarum (Szelényi & Erdös),

Diaphorina is a species-rich genus in the Old World with 78 described and many undescribed species. With over 18 known host families Diaphorina is exceptional among psyllid genera which are often restricted to one or a few related host families. Lamiaceae is an atypical psyllid host family; Ouvrard (2014) lists nine species of Lamiaceae which were cited in the literature as psyllid hosts. Five of these are, however, not confirmed by the presence of immatures and are unlikely hosts. Two, also not confirmed by immatures but likely, are hosts of Diaphorina spp., viz. D. micula Baeva, 1970 from Turkmenistan on Scutellaria bucharica and D. premnae Li, 2011 from China on Premna sp. The discovery of D. teucrii is significant in this respect as it confirms the Lamiaceae as a host family of Diaphorina. Five species of Tamarixia are reported from Israel for the first time: T. bicolor from chenopodii (), T. flaviventris (host unknown), T. pronomus from Trioza centranthi and T. urticae (outside Israel also from Bactericera kratochvili and Trioza apicalis, all Triozidae), and T. upis Walker from Trioza urticae (Triozidae). Tamarixia dorchinae is the fifth species of Israel Tamarixia. It can be distinguished from other species by characters given in the key and by having large plaque on male scape (Fig. 7).
